evaluation of perioperative anesthesia requirements of outpatient cataract patients

Conditions: Preoperative Evaluation; Outpatient; Cataract Surgery Anesthesia

Summary: according to the literature, preoperative evaluation has been shown in studies to be the first step in ensuring that patients' anesthesia care is carried out safely. in cataract surgery, which is a day anesthesia procedure frequently observed in the geriatric population, topical-local anesthesia is mostly applied. it is believed that preoperative anesthesia evaluation will be beneficial due to the complications that may develop during the procedure, patient safety and therefore the duration of postoperative hospital stay. the aim of the study is to evaluate patients who may need anesthesia intervention among patients whose preoperative anesthesia evaluations have been completed due to the possibility of consultation from the anesthesia department if necessary for patients who will undergo cataract surgery with local-topical anesthesia.

preoperative assessment is the first step in ensuring that patients receive safe anesthesia care. over time, this process has changed significantly from an era when patients were admitted to the hospital the night before surgery to a time when the majority of patients, including those scheduled for major surgical procedures, arrive on the day of surgery. outpatient preoperative assessment clinics are private and academic practices that require training in institutional staff; although common, the optimal model is unknown and may depend on the characteristics of the hospital, such as the specific types of care provided, geographic and socioeconomic differences in the population served by the hospital, patient expectations, and facility availability. the american society of anesthesiologists physical status (asa-ps) classification provides a starting point for triage. outpatient surgery may be safe even in patients with a high asa-ps classification. a multicenter european study of 57,709 procedures including asa ps iii patients found that major complications such as stroke, myocardial infarction (mi), and pulmonary embolism were extremely rare and were not clearly associated with any deaths. cataract surgery is the most frequently performed day surgery, with an estimated 3.3 million procedures performed annually by 2020 and 4.4 million by 2030. almost all are performed in an outpatient setting with minimal intravenous sedation and different local anesthesia methods. the frequency of unplanned hospitalization on the day of surgery is estimated to be 0.05%. the majority of anesthesia interventions are related to the treatment of hypertension or bradycardia. hypertension is often associated with anxiety and is often treated with sedation. rarely, bradycardia requiring treatment typically occurs as a vagal response or following intravenous sedation. considering the geriatric population and associated medical problems, monitored anesthesia care with anesthesia personnel may be considered more reliable in cataract surgery. studies have reported that the rate of anesthesia call represents 3.4% of interventions, similar to those reported in the last 15 years, but some authors have reported higher anesthesia call rates of over 20%. in literature stated that the lack of premedication probably contributed to this increase, and that other factors such as the lack of anesthesia consultation, the level of information given to the patient, the definition of the criteria for calling the anesthesiologist, and the technique applied for topical anesthesia may have also affected the rates. the studies supported the need for anesthesia personnel to be present in the operating room to be evaluated by anesthesia personnel during cataract surgery by citing the study in 406 cases, in which the rate of anesthesia requirement during peribulbar anesthesia was shown as 28.5% and interventions were typically directed towards arrhythmia, agitation, or hypertension. the primary aim of this study was to evaluate patients who may need interventions in terms of anesthesia and reanimation among those who have completed preoperative anesthesia evaluations due to the possibility of consultation with the anesthesia department if needed in patients who will undergo cataract surgery under local-topical anesthesia. investigator's secondary aim is to analyze the frequency of anesthesia interventions needed and the risk factors that play a role in these interventions by examining patient data, accompanied by patients' demographic data, medical history and preoperative anesthesia examinations.
